All you need is

INSERT INTO liba/doc#file
SELECT loc, petable.enddate, outlet,
docfunc(:loc, :outlet, :enddate)
FROM libb/sales JOIN libx/petable
ON sales.year = petable.year
AND sales.period = petable.period
GROUP BY petable.enddate,loc,outlet
ORDER BY 1,2,3

Optionally, you could have
docfunc(:loc, :outlet, :enddate) as docnum

To give the result column a name, but the names don't matter to the insert.
Only size/type.

First, Thank you.
I'm trying to avoid my typical use of an SQL cursor in a program to
loop through data to get document numbers for sales commissions (my
project for today).

Here's a (crude) example of my goal:

-- Load Document # file using SQL Function libf/docfunc INSERT INTO
liba/doc#file SELECT loc, petable.enddate, outlet,
SET docnum = docfunc(:loc, :outlet, :enddate)
FROM libb/sales JOIN libx/petable
ON sales.year = petable.year
AND sales.period = petable.period GROUP BY
petable.enddate,loc,outlet ORDER BY 1,2,3 ;

From what I know, SET cannot be used this way.
My read of the 7.1 SQL reference says SET is only used to set a host
variable ?

SQL Function docfunc returns a Document Number given: Location,
Outlet and Fiscal Period End Date Document Number identifies a
structure containing sales commission detail for a fiscal period.
petable stores fiscal period detail

Let's begin with the end in mind. What is it you are trying to do?

My limited experience using SET and reading DB2 for i SQL Reference
7.1 leads me to conclude SET can only update the value of a 'host' variable ?

And that SET cannot be used within an SQL Select ?

But, maybe, can be used within an embedded SQL Select where SET is in
a subselect or common table expression ?
